Improve Legendre functions #208

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This came up as an issue on sage-support: Legendre functions (especially the 
second kind) can be slow when the parameters are integers. mpmath should be 
using recurrences instead of hypergeometric series here. This would also 
improve numerical stability for fp evaluation.
